A process for the production of a nonwoven fabric. In particular, it relates to the production of a nonwoven fabric having desirable tactile and haptic as well as mechanical properties, as well as to the nonwoven fabric itself. The process requires the selection of specific polylactic acid polymers and corresponding process conditions.

A conductive polymeric composition includes, based on a total weight of the conductive polymeric composition, 0.1 wt % to 10 wt % of carbon nanotubes, 0.2 wt % to 4 wt % of a first component, 0.1 wt % to 4 wt % of a second component made by esterification of a C.sub.16-C.sub.30 fatty acid with a polyol compound, and the balance being a polymeric component. When the first component is a first polymer obtained from polycondensation of an aromatic diacid compound and an aliphatic glycol compound, the polymeric component is a polyester. When the first component is a second polymer obtained from polycondensation of a lactam compound, a diamine compound and a dicarboxylic acid compound, the polymeric component is a polyamide.

A biodegradable polymer usable in fishing gear and that biodegrades in aquatic environments. The polymer includes a polymer backbone that has monomeric units that are susceptible to hydrolytic degradation, and a plurality of pH responsive moieties. Each pH responsive moiety is grafted to a respective one of the monomeric units. The pH responsive moieties are relatively hydrophilic when exposed to an aqueous solution of a pro-biodegradation pH range to facilitate hydrolytic degradation of the monomeric units, and are relatively hydrophobic when removed from the aqueous solution of the pro-biodegradation pH range, to protect the monomeric units from hydrolytic degradation.

The present disclosure relates to materials, and specifically to materials such as sheet, molded or extruded polymer materials containing flake, formed, powdered, granulated or splintered borosilicate glass for heat rejection or mitigation and enhanced durability and strength. The invention provides a synthetic substrate that includes: 1 to 70 wt % borosilicate glass having an average size of 0.1 to 50 um; and 30 to 99 wt % polymer material, wherein the synthetic substrate has either a denier ranging between 0.1 to 20.0 or a thickness ranging between 0.1 to 20 MIL, which provides thermal management properties including reduction in solar absorptance and net power absorbed by surfaces. The greater the intensity of the solar radiation the more reactive the borosilicate becomes, reflecting and dissipating an increased level of energy.

A method of producing an osteoinductive bone graft formed of a plurality of electrospun biodegradable fibers is disclosed. The method includes preparing a fibrous scaffold material formed of the plurality of electrospun biodegradable fibers, wherein the plurality of electrospun biodegradable fibers are entangled with each other to form a cotton-wool like structure having inter-fiber spaces forming a microenvironment for cell growth therein, and immersing the fibrous scaffold in a solution containing BMP-2 so that the BMP-2 is bound to the calcium particles exposed on the surface of the fibers. Area of binding site for BMP-2 on calcium particles exposed on a surface of the electrospun biodegradable fibers is adjusted by an amount of the calcium particles contained in the electrospun biodegradable fibers.

This invention discloses method for feeding Hermetia illucens and used as for preparing composite material of puparium, which comprises the following steps: S1, dry Hermetia illucens pupariums and grind them into powdery, S2, adding powdery of Hermetia illucens pupariums into sodium hydroxide aqueous solution, stirring, separating and filtering, S3, adding the pupariums into hydrochloric acid solution, stirring, separating and filtering; S4, placing the pupariums into sodium hydroxide aqueous solution, stirring, separating and filtering; S5, drying the pupariums, and screening out the granular pretreated powder of the Hermetia illucens pupariums. The invention also disclose preparation method of composite material and thin film of Hermetia illucens pupariums and antibacterial and antimildew additive. The method can effectively improve the yield of chitosan in Hermetia illucens pupariums, and the prepared pupariums powder can be used for preparing polymer composite fibers and thin films of the Hermetia illucens pupariums, thus, the antibacterial effect is greatly improved. A new antibacterial and antimycotic additive can be obtained by compounding the powder of Hermetia illucens pupariums with the powder of oyster shell.
